'My invention in or relating to looms for weaving, has referenceparticularly to the type in which the use of a shuttle is dispensedwith, the weft being drawn from a cheese or the like at one side of theloom and carried upon the construction of looms of this type.

as hitherto practiced, particularly in the direction of renderinpossible the'employment of any desire plurality of wefts of differentcolours or characteristics. Further features of the invention relate tothe construction of the weft carriers and the mode of their operation;to the means for propelling and withdrawing said carriers; and to meansfor tying in or securing the ends of weft at each edge of the fabric soas to constitute selvages which will not fray.

Fig. 27 is a diagrammatic front view of the weft tying arrangement shownin Fig. 16.

I will rst describe the means by which the weft is conveyed into andlaid in the shed, and which may conveniently be referred to by thegeneral term of gripper mechanism.

This mechanism comprises two members which I shall, for convenience ofdescription, style respectively the delivering gripper and the receivinggripper, the delivering grlpper being instrumental to take a weft endrom a stationary supply and convey it part way across the shed, where itis met by the receiving gripper which takes possession of the weft endand carries it forward to the opposite edge of the fabric, thuscompleting t e laying of a pick of weft in the shed. I

v The delivering gripper comprises a pair of jaws 1 and 2, pivotedtogether at 3, the points 1 and 2 of the jaws being fashioned to grip aweft end 'w between them as indicated in Fig. 1. On the inner side ofthe gripping surfaces the jaws 1 and 2 are bent or fashioned to form arecess 4, the purpose of which will appear later, and a lateral guidepassage 5 is formed through the front jaw 1, through which the weft endmay be passed into. 'the recess 4 and thence between the grippingsurfaces 1' and 2'.

A tail piece 6 on the jaw member 2 is formed with two surfaces 6 and 6arranged, as shown, at an angle to one another, and the shank 1 of thejaw member 1 carries a bent spring 7 which is adapted to bear upon oneor the other of the two surfaces 6 or 6 and thus hold the jaws closed asshown in Fig. 1 or open as shown in Fig. 4.

The shank 1 of the jaw member 1 is detachably secured to a horizontalbar 8, a slot 1" formed vertically in the rear side of the shank beingadapted to receive a vertical projection 8 on the bar. The front side ofthe shank is formed with a longitudinal annular recess 8 (see Fig. 12')into which a correspondingly shaped spring member 9 secured to the bar 8may enter, for the purpose of holding the shank in engagement with theprojection 8 and pressed firmly against the face of the bar so that thegripper will reciprocate truly with the bar. The method of detachablysecuring the gripper shank to the carrier bar by means of the springmember 9 and of the projection 8 on the bar enables the gripper to beremoved from its engagement with the bar, or to be re-engaged therewith,by a simple vertical movement oflthe gripper. This feature is ofimportance, as will appear later, in connection with the adaptation ofthe loom to the em loyment of wefts of different colours or caracteristics.

The receiving gripper comprises a pair of jaws 10 and 11 mounted at 12on a pivot stud extending forwardly from a longitudinal carrier bar 13similar to the bar 8 which carries and reciprocates the deliveringgripper. The ends of the jaws 10 and 11 are provided with respectivegripping surfaces 10 and 11 and between these gripping surfaces and thepivot 12 the jaws are fashioned to present a recess 14 in the same waythat the jaws 1 and 2 of the delivering gripper are fashioned to formthe recess4. The jaws of the receiving gripper are arranged to open in adirection at right angles to those of the delivering gripper, as will beapparent from Figs. 1 and 2. The inner end portions of the jaws of thereceiving gripper are splayed or formed at an angle as indicated at 10and 11, and the inner end portions of the jaws of the delivery gripperare -tapered off as indicated at 1 to form a nose which, as the twogrippers are moved into contact, will engage between the surfaces 10 and11 and force the jaws of the delivery gripper apart, against the actionof a coiled spring 15 the ends of which are anchored intheshanks 10 and11 of the respective jaws.

In order that the receiving gripper as it is moved inwardly into theshed, may not foul the warp threads, I provide on its front side acurved wire 16 which will engage the warp threads at apoint somewhatnearer the fell of the fabric than the line of movement of the receivinggripper. The member 16 will thus operate to elevate or depress any warpthreads which may be out of line, and to hold them clear of the pointsof the gripper jaws. As a further safeguard in this direction, Ipreferably form the inward end of the carrier bar 13 for the receivinggripper with an enlargement or spear head 13 as indicated in Figs. 2 and3. Any misaligned warp threads will be engaged by the angular faces 1313 of this enlargement or spear head and will be deflected clear of thegripper jaws.

The action of the grippers will be apparent from Figs. 1 to 4 and is asfollows :-Figs. 1 and 2 assume that the delivery and receiving grippersare moving together or towards one another through the shed, the aws ofthe delivery gripper having gripped between them the end W of weft anddrawing from the stationary supply as the delivery ripper 'moves towardsthe centre of the she The grippers are arranged to meet at orsubstantially at the centre of the length of the shed, the receivinggripper being preferably timed to arrive slightly before the deliverygripper, so that when the latter arrives at its inward limit of movementthe receiving gripper is positioned, and stationary, to receive it. Asthe tapered nose of'the delivering gripper comes into contact with thesurfaces 10 and 11 of the receiving ripper jaws, it forces said jawsapart and t e nose passes into the recess 14, as indicated in Fig. 3,the gripping surfaces 10 and 11 of the receiving gripper closing downunder the action of their spring 15-upon the weft end extending acrossthe recess 4-. The receiving gripper now commences its outward movement,slightly in advance of the delivering gripper. This causes the inhersides of the grip ing surfaces 10 and 11',

' which are suitably s aped as indicated at 10 and 11 to be brought intocontact with the respective jaws 1 and 2 of the delivery gripper, at theinner end of the recess 4., The action of the surfaces 10' and 11*, inco-operation with the taper of the recess 4:, is such as to force themovable jaw 2 away from the fixed jaw 1, as indicated in Fig. 4,the-surface 6 being moved away from, and the surface 6 moved beneath,the end of the sprin 7. The gripping surface 2 of the jaw 2 is t us heldclear of the gripping surface 1 of the jaw 1. The grippers continue tomove apart until they clear the selvages of the fabric, the receivinggripper drawing weft freely through the passage 5.

It will now be convenient to describe with the aid of Figs. 5 and 6 themeans by which the carrier bars 8 and13 are operated. J

Gripper-reciprocating mechanism As the mechanism for moving each of thecarrier bars is similar, it will sufliceto describeone mechanism, andthat for moving the carrier bar 8 for the delivering gripper will bedescribed. It may first be mentioned that each bar 8 or 13 is supportedfor horizontal sliding movement in a horizontal guide mounted on a stud26 on an arm of the rocker 21. An arm 27 fast with the pinion 25 ispivotally connected'with the stick 18 at 28. A connection 29, operatedby a suitable crank motion at the centre of the loom is pivotallyconnected to the quadrant at 29'. The necessary dwell of the carrierbar, requisite for the change of shed and so on, is provided for by aplain or untoothed surface 24' on the quadrant, which co-operates with aplain segmental portion 25 on the pinion 25. As the connector 29 isdrawn inwardly, it swings the quadrant, and causes the toothed portionthereof to be brought into mesh with the teeth of the pinion 25. Thepartial rotation given to the latter causes the arm 27 to swingdownwardly,- as indicated in Fig. 6, and the roller v19 on the stick 18to move vertically downwards in the slot 20. The pivot pin 18 by whichthe stick 18 is connected to the bar 8 is thus caused to traverse a truehorizontal path and no strain is imposed upon the guide in which the barworks. i

As above mentioned, the carrier bar 13 for the receiving gripper isoperated by a mechanism similar to that just described for operating thebar 8. The connectors by which arms being so set that the receivinggripper moves slightly-ahead of the delivery gripper, as mentioned inthe description of the gripper mechanism.

In order to check the inward movements of the grippers, I employ at eachside of the loom a device such as illustrated at Fig. 15. This comprisesa weighted disc 30 pivotally mounted on the lay and having pivotallyconnected to it at 31' a bar 31 having a curved end portion 31 A leatherstrip 32 secured at one end to the bar 31 has its opposite end bent asshown over the end of the curved bar portion 31 so that a space 33 isformed between the leather strip and the bar end. A pin 18','on theoperating stick 18 of a gripper, is adapted to strike the leather strip32 just before the gripper reaches its inward limit of movement. Thiscauses the bar. 31 to move inwardly and to rock the disc 30 about itspivot. The pivot centre of the disc, the point of. connection of the barto the disc, and the centre of the in 18 being brought into alignment,.the eather strip 32 acts to check further inward 'by a strap 34 loopedabout the stick 18 and.

a out a part of the lay or going part.

Gripper opening and closing means As previously described, thedelivering gripper makes its outward movement open, so that thereceiving gripper may draw the weft freely through the passage 5. As itarrives back at the outward limit of its movement, it is necessary toclose it again uponthe weft, ready for the next inward movement. This iseffected by means of a short lever 35 pivotally mounted, as at 35?, atthe back of the lay and having an engaging end 35 adapted, as the leveris swung appropriately about its pivot, to move forwardly and pressagainst the open jaw 2 of the delivery gripper. The jaw 2 is thus closedupon the jaw 1 and the surface 6 brought beneath the spring 7, so thatthe jaw is maintained closed and a grip exerted upon the weftend. Thisclosing movement is effected just as the gripper ceases to moveoutwardly, so that no pull is exerted on the weft end extending throughthe shed to the receiving gripper. The lever 35 is operated by thecontact, with a depending projection 35 thereon, of a spring contact 36on a bar 37 extending rearwardly from the breast beam 38. This springcontact yields after it has swung the lever 35 and passes beneath thelower end of the projection 35 as the lay continues its forwardmovement, a suitable spring 35* on the pivot of the lever 35 acting toreturn said lever to normal position after it has performed itsfunction. As the lay goes back, the contact 36 yields to permit of thepassage over it ofthe projection 35".

The receiving gripper moves outwardly carrying the weft end it has takenover from the delivery gripper. It is necessary that, when the receivinggripper reaches its outward limit of movement, it shall relinquish itsgrip on this weft end, to permit of the inserted weft being beaten up,and to prepare it for its next inward movement to receive a new weft.The requisite opening of the aws of the receiving gripper is effected bya member 39 pivotally mounted at 39 on the lay and having connected toit a radius rod 40 which works through a block 41 mounted pivotally onthe breast beam. A collar 42 secured on the rod 40 abuts against-theblock 41 as the lay approaches front centre and causes the member 39 toswing inwardly. A

rearwardly bent portion 39 ofthe member 39 is thus swung upwardly into aposition to enter between the shanks of the receiving gripper aws asthereceiving gripper moves outwardly, and forces the jaws open. As thelay goes back, the member 39 1s swung outwardly by a suitable spring andthe portion 39 thereof is moved from between the gripper shanks,permitting the gripper jaws to c ose again ready for the next inwardmovement.

I have now described the gripper mechanism and its operation, and themeans by which the grippers are reciprocated and their jaws opened andclosed. I will now describe the means by which the weft end is severedbetween the delivery gripper and the selvage of the fabric, and by whichthe ends of weft projecting beyond the edges of the fabric at therespective selvages are dealt with.

Weft-cutting and seloage foaming means Mounted between the edge of thefabric and the outward position of the delivery gripper is a rotarycutter disc 43 into contact with which the weft is brought as thedelivery gripper closes upon it and continues to move forwardly.

Rotation of the cutter disc 43 is effected as follows :--On its axis isa small pulley 44 about which passes a cord 45. One end of this cord isconnected to a spring 46 anchored on the breast beam, and its other endis connected to one arm of a-bell crank lever 47 pivoted at 48 to thesupport 43' for the cutter disc 43. The other arm of the bell crank 47has a part 47 adapted to be engaged by an abutment 49 on the lay as thelatter heats up. As a result of this engagement the lever 47 is rockedabout its plvot and the cord v is drawn downwardly. This causes arotation of the disc 43 and an extension of the spring 46. As the layrecedes, the contraction of the spring 46 draws back the cord 45 andreturns the lever 47 to normal position; a stop 43" on the support 43'limiting the movement of the lever 47. The rearward end of the support43 has a slot 43 with a bell mouthed entrance 43 to guide in the weft tobe out.

As the means for dealing with the projecting weft ends at the two sidesof the loom are similar, it will suffice to describe one of them. Thatat the right hand end of the loom will, therefore, be described. The cap50 of the temple 51 is formed with a block 50 having a cylindrical borein which works a spindle 52. In the periphery of this'spindle is formeda spiral groove 52' into which enters the point of a set screw 53screwed into a threaded opening in the block 50 to project into the borethereof. An annular groove 52 at the front end of this spindle receivesthe forked end of a spring blade 54 mounted on the breast beam; and anupwardly bent member 55 secured to the abutment 49 on the lay is adaptedto engage the blade 54 as the laybeats up and to move the spindle 52frontwardly with a consequential partial rotary movement. .The rearwardend of the spindle 52 carries a wire 56 the rearward end of which iscurved and fashioned to form a bill 56 with a thread engaging extremityor hook 56 This bill 56 is positioned, as shown, above the edge of thefabric, and it is adapted when rotated and drawn frontwardly, to seizehold of the weft end, which at this moment is extending across andadjacent to the cutter 43, and to whip such end when severed into theshed and carry its extremity up between the upper warp threads of theshed at a short distance from the edge of the fabric, so that onthe beatup it will be secured. In order that the bill may have something tooffer the requisite resistance, about which to loop or turn inthe weftend, I provide outside the warp edge a strong thread 57 independent ofthe warp and forming part of the .selvage, and which can be raised andlowered by means of a suitably operated cam motion. The operation ofsecuring the weft ends, and the function and operation of the strongthread 57 will be better understood by reference to Figs. 9 to 11 and24. In Fig. 9 the weft W is shown as extending out through the openshed, the thread 57 being at this time lowered. The thread 57 is thenraised as shown in Fig. 10 by a cam or other suitable-motion, elevatingthe weft slightly as indicated and giving room beneath it and betweenitself and the lower warp threads for the passage of the engaging end ofthe bill (Fig. 7). As soon as the thread 57 has been raised, the spindle52 receives its frontward and rotary movement, with the result that theweftend is brought into contact with the cutter and is severed andcarried round beneath the raised thread 57 as a pivot, the extremity ofthe severed end being carried up as shown in Fig. 11 between two warpthreads at a short distance inwardly from the edge of the fabric. Themanner in which the engaging end of the bill passes down between theupper warp threads and beneath same and the strong thread 57 to takehold of the weft end as it is out is shown in Fig. 7. The rear end ofthe groove 52 in the spindle 52 is made parallel with the spindle axisfor a short distance, as indicated in Fig. 8, so that when the bill haswhipped up the extremity ofthe weft end in the manner indicated it isdrawn forwardly a short distance so as to be clear of the reed as thebeat up takes place. As the lay recedes, the bill moves straight backfor a short distance until the new shed has the exception of course,that the spindle carrying the b1ll rotates in the opposite direction.The ends of the weft which project above the fabric may be cropped ofleither on the loom or subsequently during the finishing of the fabric.

- As an additional security in the direction of tying in the weft ends,the means illus-' trated at Fig. 16 may be employed, or such means maybe employed alone for the purpose. The means referred to comprise a pairof bobbins 58 and 59 the spindles of which are carried by a chain or'band 60 extending around a pin or roller 61 and a wheel 62, the latterreceiving intermittent partial rotations by gears 63 and 64 from a starwheel 65 operated froma suitable moving part such as a jack or lever ofthe loom dobby. The threads 58' and 59 from the bobbins 58 and 59 areled through a ring 66 and then through eyes 58 and 59 in the ends of therespective bobbin spindles, after passing through which they are ledaround the stout thread 57 or around one or more of the warp threads atthe edge of the fabric. Each operation of the star wheel 65 is arrangedto reverse the positions of the bobbins 58 and 59 with the result thatthe threads leading from the bobbins are gradually drawn 0E and twistedaround the thread 57 or such of the, warp threads as may be concerned,between each insertion of weft, the weft ends being thus tightlygripped. The parts just described will conveniently be mounted in rearof the reed, and be carried say by a bracket attached to the loom frame.The thread 57 may pass through the ring 66, and for each step of thestar wheel 55, the chain 60 moves through one-half of its circuit,thereby reversing the bobbins 58 and 59. This not only produces a halfturn of the threads 58' and 59' around the thread 57, but the threads 58and 59' are also'alternately moved to opposite sides of the thread 57,similar to the formation of the warp shed,

so that the wefts may pass between the threads 58 and 59. The twistingof threads 58 and 59v will therefore tie the wefts to the thread 57, orsimilarly around one of the warp threads, the device shown in Fig. 16being operable on the strong thread 57 or one or more warp threads, ormay appl the threads 58' and 59' to the wefts on y, as seen in Fig. 26.Fig. 25 shows the threads 58 and 59' twisted around the strong thread 757 and binding the wefts thereto.

The description so far applies equally to the employment of a singleweftor to the employment of a plurality of different wefts.

It only remains therefore to describe the means whereby the employmentof a plurality of wefts is rendered possible.

Multiple weft arrangement The use of a plurality of wefts is arrangedfor by providing at the right hand end of the loom a vertically movablecarrier box 66 conedge a notch 68 (see Fig. 1) corresponding in width toor slightly larger than the bar 67. The box 66 is connected by a link 69with suitable mechanism controlled by a dobby,

' pattern chain or therlike, whereby the said box may receive verticalmovements to present opposite the weft delivery line the cell or chambercorresponding to the weft of the colour or characteristic called for.The box 'movements take place when the carrier bar 8 is in outwardposition, so that when by a box movement the delivery gripper which hasbeen active is detached from the spring holder 9 another deliverygripper is moved into position opposite the carrier bar and in so movingis engaged and held by the spring 9 in position over the projection onthe carrier bar- The engagement of the non-active delivery grippers, bythe entry of the bar 67 into their vertical notches, holds them in thecarrier box during their periods of non-activity and maintains them incorrect position for reengagement with the carrier bar when called uponby the indications otthe box pattern mechanism. Each delivering gripperdraws its weft from its own source of supply, and it will be apparentthat any number of cells beyond the four indicated and additionaldelivering grippers maybe provided according to the variety of coloursor characteristics of weft it is desired to employ. p 7

Where :a plurality of wefts are employed, or even where a single weft isemployed, it is desirable to provide means to take up the slack, andconsequent curl, of the weft which occurs during the beat up of the layafter the receiving gripper has ceased to draw off, and the deliveringripper has closed again upon the Weft. igs. 19 and '20 illustrate onemeans for supporting and dealing with plurality of weft supplies.

A frame 7 0 ada to hook over the breast beam has a nnm er of verticalspindles 71 corresponding to the number of wefts to be used. An invertedU-shaped member 72, pivoted to lugs 73, 73, on the breast beam, has aconnection 74 to the lay. The ends of weft from the several bobbins onthe'spindles 71 are led through guide eyes 75 and through openings 7 2'in the cross-bar of the member 72. As the lay swings forwardly andrearwardly, the member 72 swings with it, and by its pivotal movementtakes up the slack.

* The ends of weft extending from the member 72 are preferably ledthrough a vertical guide 7 3 Figs. 7 and 8 secured to the carrier box 66and provided with therequisite member of appropriately spaced guideopenings.

It will be apparent that, although the fore; going describes one goodpractical embod1- ment of the invention the details of construction andarrangement of the parts employed inay obviously vary in many waysaccording to the kind of fabric to be woven and to suit 7 individualrequirements. p
